This could be the perfect accessory in any home or office. While providing a very functional calendar, it makes paper calendars obsolete! Not like ordinary perpetual calendars with bunches of tile pieces for the days, this one uses much fewer pieces, and is configured much faster! Simple enough for children to set-up each month - not a time-comsuming chore - and in block form, so they'll actually look forward to it!
The plans also include a handy desk version - a daily calendar, which uses only 2 blocks to set the days. If built of the same material, they can compliment each other in function and design.
